This invention relates to a power operated earth working tool especially designed for use in road building and maintenance.

An object of the invention is to provide an improved means for imparting ower to the earth-working element. A furt er object is to provide a simple and eifective means for. pushing the earth-working element; such means being adapted to relieve unnecessary stresses in the frame. A further object is to provide a more direct driving connectlon between the traction elements and the earth- Working element. A further object is to provide a mounting and controlling means for the earth-working element including a circle and to mount said earth-working element at the front of such circle whereby to provide greater working clearance in front of said earth-working element. A further object is to provide a push bar for driving the earth-working element which will be rigidly connected to said circle and universally connected with the rear portion of the "ehicle on the housing means associated with the rear axle means. A further object is to provide a connection between a rear traction element and the earth-working element whereby the axle of said traction element shall be in line of thrust from said earthworking element. A further object is to provide an improved disposition of the power plant, earth-working element, control means and drive for the earth-working element, whereby the latter will be clearly visible to the operator. A furtherobject is to provide an im roved power transmission means adapted for cooperation with the other improved features for rendering the entire tool more flexible and easil controllable and for securing a better positioning of the parts to avoid undesirable proximity of the moving parts to the work.

Other and more limited objects will become apparent from the following description taken in connection with the accompanying drawings in which Fig. 1 is a side elevation of the present preferred embodiment of my invention omitting certain parts; Fig.2 is aplan view thereof; Fig. 3 corresponds. substantially to a section in the central region looking forward and omitting the front of the frame and the power plant; Fig. 4 is a bottom plan view of one-half the mounting and controlling circle; Fig. 5 is an enlarged vertical sectional view taken through the transmission and rear axle means; Fig. 6 is a top plan view of the portion of the device shown in Fig; 5 showing the central part in section at substantially the level of the rear axle means; Fig. 7 is a fragmentary vertical section taken through the transmission and rear axle means at substantially right angles to the showing of Fig. 5; and Fig. 8 is a detail sectional view on an enlarged scale, at the level of the secondary drive shaft.

Referring now to the drawings wherein similar numerals indicate similar parts in the various views, the numeral 10 indicates an upwardly arched frame of a power vehicle. This frame may consist of a pair of channel members as indicated or any other equivalent construction such as a single tube or the like. Mounted in any'suitable manner at the front of the frame is a power plant indicated generally by the numeral 11, including the usual internal combustion or other suitable motor and conventional associated mechanism. Also secured to the frame 10 at the front thereof is an axle 12 carrying a pair of Wheels 13 or equivalent mechanism provided with steering mechanism of the conventional type including steering knuckles 14, tie rod 15, drag link 16, together with the usual steering worm construction 17 carrying an arm 18 and being connected in the usual manner with a steering post 19 which carries at its upper end a steering wheel 20. It will be understood that the steering post and worm 17 are secured to the frame in any suitable manner.

The fuel tank 21 may be disposed adjacent the power plant as indicated, being braced by a member 22 secured to the frame of the vehicle. Secured to the motor housing and to the vehicle frame is a clutch assembly schematically indicated at 23 and controlled by means of lever 24, link 25 and bell crank foot control lever 2t Extendmotor is a drive inclusive, a principal housing element ineluding a portion adapted to house the gearing assembly which is connected tothe axles, a transmission housing 29, a cover plate 30, axle housings 31 and a earth-working element driving boss 32. As best indicated in Fig. 7, the frame 10 is secured to the axle housings 31 by means of fixtures 33 which include U bolts 34 extending around such" axle housing members. It is to be undere stood that the frame may, within the contemplation of my invention, be secured in any other suitable manner. Additional connection may also be made between the transmission housing and the frame as'by means of an angle iron extending across the frame and secured to said housing.

Extending through the axle housin 31 are axles 35 mounted in any suitable ind of bearings and connected to traction elements 36 which in the drawings annexed hereto are represented by wheels but which may consist of crawlers of the endless chain type or any other suitable traction means. The axle means 35 may be in two parts and driven through a differential mechanism or in one part and driven by a gear fixedly attached thereto.

In the drawings, I have illustrated a bull gear 37 which may be connected rigidly to a single axle means extending through and connecting both traction elements 36 or may be the ring gear of a differential drive or transmission which will' allow difl'erent speeds of rotation for the two traction elements.

Mounted directly above the axle means 35 is a slidable-pinion 38 meshing with the bull gear 37 and slidableron a shaft 39 whichis mounted in suitable bearings 40 carried by the transmission housing 28. The pinion 38 is reciprocated by a member 41 slieably mounted on a bar 42 and controlled by a lever 43. The member 41 s provided with a bifurcated terminal portion which engages in a groove 44 in the sliding pinion ed receive the ends of the teeth 47 of the shding pimon 38. It is to be understood that any other suitable clutch means may be employed. Meshing with both the beveled gears is a beveled pinion 48 nonrotatably carried by a secondary drive shaft 49 upon which are also mounted a plurality of different sized speed change transmis sion gears 50. It is to be understood that the bevel gears 45 are spaced apart such a Slidably but non-rotatably mounted on the.

shaft 51 are correspondlng change speed gears 52, which are adapted to be controlled by any suitable mechanism, for engagement with the gears to secure a change-in speed.

As indicated in Figs. 5.and 6, the central portion of the housing 28 which receives and secures the housing members 31 is provided at the front with a boss 32. A plate 53 contacting the boss 32 is provided with a hemispherical concavity 54 adapted to receive a ball 55 which is held in position by a securing late 56 having a part spherical portion 5 and allowing a universal movement of the ball 55 and the member 58 to which it is connected by a neck 59. The plates 53 and 56 are secured to the boss 32 .by suitable bolts (not shown). 5

Attached to the'member 58, as by rivets 60,. is a chahneled push member 61 which extends forwardly. The member 61 is provided near its front end with an opening as indicated in Figs. 2 and 3 through which extends a bushing 62 which receives a bolt- 63 and abuts the head of said bolt and a hub 64 of a circle 65. The circle 65 includes, in addition to the hub 64, a flat circular portion 66, provided with notches 67 adapted to receive a latch member, and reinforcing bands or ribs 68 and 69 either welded or otherwise secured thereto or integral therewith. The member 69 is provided with a pair of forwardly projecting arms 70 in direct continuation of the circular portion 66 and extending downwardly as best. seen in Fig. 1.

ivotally connected to the ends of the arms 70-are brackets 71 which in turn are rigidly secured to an angle member 72 whichv carries a curved earth-working element 7 3..

Pivotally secured tothe arms 70 are links 74 which are in turn ivoted to lugs 75 on the curved earth-wor ing element 73. The earth-working element 73 may also include a separable blade 76. It is to be understood that other earth-working elements may be substituted for the curved blade and mold board constructions shown and that such tools as the conventional scarifier or the like /leo may be substituted. In the event such substitution is made, the mounting construction may be suitably modified.

Slidably mounted with respect to the channel member 61 and resiliently urged forwardly by a spring (not shown) is a latch element 98 which is adapted to engage in v and 78 which approach each other at their outer ends and are secured in spaced relation and adapted to receive pivotally blocks 7 9 to which are pivoted connectors 80 which are universally connected to arms 81. The arms 81 are non-rotatably carried by shafts 82 upon which are mounted gears 83 controlled by hand wheels 84 through the medium of worms 85 all of which'are carried by castings 86 mounted on the frame 10.

A transverse bracing member 87 may be provided extending between the two frame members 10 and connected thereto. Extending between the frame members 10 is a bar 88 provided with a series of openings 89 and adapted to receive a slider 90 between which and the straps 77 and 78 extends a link 91' adapted to absorb side thrust on the'earthworking tillage element. I

It will be noted that the steering wheel 20, the hand wheels-84, the clutch control 26, the latch control 92, the gear shift 93 and the reversing shift 94 are brought to the same region whereby to be in convenient reach of the operator standing on the platform 95 which is pivoted to the frame members 96 and resiliently supported thereby at 97.

It should be noted that the control station, by which term is to be understood the operators platform 95 and the control element positioned within his reach when standing there, is positioned somewhat back of the earth-working element whereby the latter is v in position for most convenient observation by the operator.

From the foregoing, it will be clear that I have provided a power operated earth working tool which is well adapted for its in tended purpose. It is believed that the operation will be clear from the foregoing and need not be further elaborated.
